Wildly paranoid about making a mistake validating tickets with trenitalia. my daughter recently had bad tram experience in nice and couldn't prove validation. I'm likely comparing apples to oranges but I know this is newer process.
I have four sets of timed tickets purchased already and two of the journeys do not include qr codes ("not valid for travel").
they require activation day of travel. is this complicated and if i'm having trouble with the app can it be done via the web site? anything i should know?
and, for the ones tha have pdf's with qr codes I'm good to go? Right? Just board train?
Thanks in advance
